1.HOUSEKEEPING - These are the most common type of dream
and the least memorable. These serve to keep the contents of the mind
in order and to fit new contents into an appropriate space. They help
to minimise emotional disorder by, eventually, putting things into perspective.

2.DIAGNOSTIC/ILLUSTRATIVE - These are rarer dreams...They
are heavily coded messages from the deep subconscious. They show things
as they are, and are often richly coloured and structurally complex....

3.PROPHETIC - These are rarer still. These are basically
time- displacement dreams in which I may relive a past event (e.g. my
emotions at the age of eight) or may experience something that happens
to me in the future (e.g. déjà-vu).Enchanted Diary [p.2027] (As recorded in "Torchlight
in a Dark Space" RM4.)

"...most people now agree that dreams bring in old and new experiences.
We know it's in the deep sleep that we learn. Dreaming is not about learning
- it seems to be about areas of conflicting emotions. It's updating our
interpretive systems of the world."
Professor Horst Kachele as quoted in "Dream Time : Why Freud is fashionable
(again)" from The Australian April 3-4, 1999.

4)."...I have problems with dream interpretations....I look on dreams...as
the mind's way of reordering things - putting them back in their compartments,
maybe dealing with some problems that have been nagging at you. By and
large I see attempts at interpreting dreams as reading too much into what
has happened - trying to impose conscious order on something that isn't
capable of being ordered."

(ANZAPA 185). December 1998. [p.20]

5)."Think fantasy. There's nothing new; everything in your head
is programmed by the familiarity of mythology, and has been for more than
a million years."

now.)

Have you ever looked at one of those floors covered with patterned tiles?

If you have - you might have realised something interesting: your eyes
are constantly moving over the tiles, and you are mentally grouping them
together in various ways, and always always looking for patterns.

The brain, while you are awake, never stops gathering and attempting
to interpret sensory data - and it goes further than that.

Your brain interprets events - looks for cause and effect, works out
consequences. When we interact with others - we comprehend language and
gestures; receive and communicate information, opinions and feelings;
and actively try and work out the psychology of others and their motivations.

This is a lot of data-processing! (And we are not born 'knowing' - we
have to learn how to perceive, how to speak, how to interpret the actions
of others.)

Human beings are reputed to have deep down rules-of-thumb, short-hand
ways of interpreting the world. These are called heuristics.

In brief - we carry around in our heads a sort of 'working model of the
world.' It is simpler than the real thing - and we have created it ourselves.

Why do we sleep? The psychologists have carried out experiments in sleep
deprivation. When people are deprived of sleep they become irritable,
they lose their powers of concentration and become confused. They begin
to hallucinate - effectively to have waking dreams.

In animal experiments - long term sleep deprivation leads to death!

So sleep is very very important for mental health and correct brain function.

What happens when we sleep? (I won't talk about sleep-cycles, REM sleep
and all that here.) When we sleep - we dream.

To put it simply - when we dream we are pulling apart and rebuilding
that 'working model of the world' we have inside us.

We are pulling it apart so that we can put new things into it. We are
sorting through the days accumulated impressions and letting some of them
go (drifting into the unconscious), and putting other portions (which
have been somehow marked as important) into our model.

But dreams can indicate far more than the sorting of memories - that
is why they are can seem so strange.

As indicated in the introduction - I believe that the majority of dreams
are these 'Housekeeping Dreams.' They are important for mental health,
but there is no reason for us to remember them: this is why we generally
don't.

(Of course how much of a dream we remember relates to when in the sleep
cycle we are woken up. If we drift into dreamless sleep after a dream,
the residues of the dream will be washed away like castles on the seashore).

What sorts of things are contained in the 'working model of the world'
we carry in our heads?

The important things to remember at the very beginning are:

1). The model originated in the womb (may even have had a basic template
which was inherited - somehow encoded in our DNA), and has been worked
on by us ever since.

2). The model is a lot simpler than the world around us - but, paradoxically,
contains many things the world around us does not have.

3). The model is largely atemporal. (This is one of the ways it is simpler
than the world). Grief, for example, touches our real lives at many points,
but in the model grief is brought together in one nexus. In a sense all
griefs are one grief. (This explains why we tend to follow the same routines
in similar situations, and also why traumatic situations dredge up repressed
memories of similar happenings.)

4). The model is elaborate, but very logically constructed. (It
employs massive nets of associations. Each element in it is linked to
very very many other items. It is, after all, a model to think with!)

5). The model contains lots of other littler models!

6). Using the model is as natural to us as breathing.

So - what does the model contain?

1. Memories stretching back to before we were born. (The amount
of detail varies. Conscious and pre-conscious memories tend to be skeletonised
- basic events remain. Colours and emotions are filed elsewhere - much
drifts into the unconscious).

I want to discuss trauma. I want to discuss when things aren't going
well - when we are confused and unhappy and worried, and we don't know what to
do about it.

In short - when we have a problem.

As hinted at before the brain is constantly working to solve problems.

What do we do when we use all the knowledge we have of the world and
of our situation, and our 'working model of the world' still fails us?

In conscious life we will seek out new information, we will talk to people
(seek counselling), and ponder and ponder and ponder.

In unconscious life - well:"We are dreaming all the time, and consciousness is an additional
feature." [Kachele][3]

When we go 'offline' something truly remarkable occurs.

I mentioned before how during sleep we are tinkering with our 'working
model of the world' making adjustments and adding new material.

In a stress situation this activity is far more frantic and far more
extensive. Large chunks of the model are pulled apart, and hidden recesses are exposed
and ruthlessly explored. Heaps of stuff is brought up from the unconscious, in
the hope that something previously discarded can be fitted into the model.
Can be fitted inside to make the model work properly - to make a model
which provides us with a route to a harmonious outcome.

That is what the inner us wants - harmony, happiness, "wings of
brightness."

The elements in our 'working model of the world' are related to each
other in very complex ways.

During the process of reasoning we leap from idea to idea - but each
new idea is linked to its precursor: though the relationships may be pretty
abstract.

It is the same with the 'working model' - all its elements are related
to other elements. (I suspect it's a many-to-many association.)

Here is the rub - Does irrationality exist in the brain? Does nonsense?
Or are we dealing with strange deeply-convoluted sets of associations?

In short - is the brain chaotic? If it were chaotic - could it still
work?

Yes - and no. There are (apparently) random misfirings of neurons in
the brain. [Some scientists speculate that these somehow assist creativity
- i.e. new random thoughts. I suspect that since the brain exists in the "real
world" it must be able to deal with some electrical "noise."]

The key to this mystery is consciousness. We can choose which paths to
follow through the nest of associations - though we are often lead. [I
might tackle conscious and 'automatic/habitual' thought another time.]

Now - dreams are not usually under conscious control. They will follow
natural paths only. ('Natural' does not mean easy or familiar - they can
be difficult and unsettling paths.)

The paths - as previously hinted - are links of associations. (The
associations are previously mapped either by reason (conscious thought)
or by experience (unconscious perception).) This implies that there is an 'inner
logic' to dreams - there is a progression and the contents have relationships.

Have you got all that? To recap:

1. Dreams work with our 'working model of the world.'

2. Objects in this 'working model' are all linked by associations.

3. There is a 'natural path' that can be followed from object to object
in the 'working model.' This path displays an inbuilt logic.

The whole purpose of our 'working model of the world' is to make sense
of the world around us, so that we can work in it to attain our goals.

It doesn't take an enormous intuitive leap to realise that this model
is what gives meaning to our life and our universe? (Since meaning is
something we impose on inanimate matter by an act of consciousness). [4]

The 'working model' deals with "meaning" in the old-fashioned
existentialist meaning of the word. Since dreams work upon this model, it can be surmised
that they do in fact 'have' meaning.

Interpreting that meaning is quite a different exercise. I feel quite
happy in leaving that to another essay.

[1]. Unfortunately I couldn't find the newspaper article
about James Watson and his theory when I was preparing this essay, so
I couldn't quote him directly.

[2]. Invaginated Shadow Mind.
I'm still convinced that this thing exists - and is quite a different
thing from the simple conscious and unconscious, and left and right hemispheres.

[3]. That article from The Australian again. Has
many thought-provoking quotations. Here's another:Fonagy says that the main insight from Freud on dreams remains that
he showed there is an aspect of the mind that can be understood, but to
which we have no conscious access. "What we now know is that something
like 95 per cent of the brain is active without us having any idea what
it's doing," he says. "The vast bulk of the activity of the
brain we haven't a hope in hell of ever knowing about."

[4]. "Since meaning is something we impose on
inanimate matter by an act of consciousness."

Of course the existence of God would change the nature of the argument
- but I'm not confident of tackling that issue. (I'd have to probe exceedingly
deep into the nature of reality and see whether God pops up!)
